It’s always very encouraging in an investigation to find new family archives relating to the person or the subject we study. It’s because of this reason that the particular case of Martí Alsina it’s been so special for the scientifi c world. They are about three thousand handwritten papers from the painter and its relatives that offer us information either private, personal, professional, social and political, artistic or bureaucratic. That is to say, all kind of information able to let us feel and see with our own eyes how this passionate and unsettled painter was. This article wants to be an example of the news that the two unpublished archives offer us, the one unknown and included in my doctoral thesis; and the other, that fortunately has been deposited in the Museu Nacional d’Art de Catalunya.
